Factors contributing to events in NSW on Thursday 23rd January 2020 – taking a closer look…
Today I managed to get about half-way (only!) through some analysis I wanted to do to ‘scratch that itch’ about what happened in the NSW Region on Thursday 23rd January – with LOR2 conditions necessitating RERT (Reserve Trader) in the NSW Region.
RERT dispatched in NSW this afternoon, plus other things (at 15:55)
